This index combines the advantages of the Super Index with those of
a worm-geared index. When mounted on a milling, boring or other
machine tool it can carry out single-purpose indexing and indirect
indexing using the worm-drive mechanism. Disengaging the worm drive
the 24-notch master plate permits 2,3,4,6,8,12 and 24 dividing in
the same manner as the Simple Index. When the chuck is removed, the
unit can be used as a horizontal and vertical type rotary table.
The operating handle to rotary table worm gear reduction ration is
1:90. The operating handle collar is graduated in one minute, and
readings down to ten seconds can be set on the verier.
